Frank Goossens on "[Plugin: Autoptimize] Javascript still has comments"

Well, you would have to hook into the filter like this;

add_filter('autoptimize_js_after_minify','kokomoweb_js_after_minfy',10,1);
function kokomoweb_js_after_minify($jsIn) {
	$jsOut=fancy_code_to_remove_important_comments($jsIn);
	return $jsOut;
}

where fancy_code_to_remove_important_comments would probably be some smart regular-expression to remove everything between (and including) /*! and */.

Feel free to share your result here for others to enjoy! :-)

Have fun,
